● Prior to the installation, please make a good preparation for all piping (refrigerant pipe,
drain pipe) and wring (wires of the wired controller, wires between the indoor and outdoor
unit) of the indoor unit to make the further installation much easy.
● If there is an opening in the ceiling, it is better to reinforce it to keep it at and prevent it
vibrating. Consult the user and builder for more details.
● If the strength of the ceiling is not strong enough, abeam made of angle iron can be used
and then x the unit on it.
● If the indoor unit is not installed in the air conditioning area, please use sponge around the
unit to prevent condensing. The thickness of the sponge depends on the actual installation
environment.
1. Cut the connection pipe with the pipe cutter and remove the burrs.
2. Hold the pipe downward to prevent cuttings from entering the pipe.
3. Remove the are nuts at the stop valve of the outdoor unit and inside the accessory bag
of the indoor unit, then insert them to the connection pipe, after that, are the connection
pipe with a aring tool.

2. Do not bend the pipes in an angle more than 90°.
3. When pipes are repeatedly bent or stretched, the material
will harden, making it difcult to bend or stretch them any
more. Do not bend or stretch the pipes more than three
times.
4. When bending the pipe, do not bend it as is. The pipe
will be collapsed. In this case, cut the heat insulating
pipe with a sharp cutter as shown in Fig.14, and bend
it after exposing the pipe. After bending the pipe as
you want, be sure to put the heat insulating pipe back
on the pipe, and secure it with tape.
Detach the caps and plugs from the pipes.
Centering the pipe against port on the indoor unit, turn the are nut with your hand.

● To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of
curvature of 150 mm or over.
● If the pipe is bent repeatedly at the same place, it will break.
● Be sure to apply the pipe against the port on the indoor unit correctly. If the centering is
improper, the are nut cannot be tightened smoothly. If the are nut is forced to turn, the
threads will be damaged.
● Do not remove the are nut until the connection pipe is to be connected so as to prevent
dust and impurities from coming into the pipe system.
Hold the torque wrench at its grip, keeping it in the right angle with the pipe as shown in Fig. 12,

Installation Instructions
2. The default installation location of the rectangular ange is at the back and the return air
cover plate is at the bottom, as shown in Fig.25
3. If the bottom return air is desired, just change the place of the rectangular ange and the
return air cover plate.
4. Connect one end of the return air duct to the return air outlet of the unit by rivets and the
other to the return air louver. For the sake of the convenience to freely adjust the height, a
cutting of canvas duct will be helpful, which can be reinforced and folded by 8# iron wire.
5. More noise is likely to be produced in the bottom return air mode than the backward return
air mode, so it is suggested to install a silencer and a static pressure box to minimize the
noise.
6. The installation method can be chosen with considering the conditions of the building and
maintenance etc., as shown in Fig.26.
